It was an ancient parish in the county of Middlesex and has been part of Greater London since 1965.
The manor is described in the Domesday Book (1087), but the name 'Hendun' – meaning 'at the highest hill' – is of earlier origin. There is also evidence of Roman settlement within the area.
The Midland Railway and the Great Northern Railways were built through Hendon in the 1860s. The London Underground (Northern line) arrived at Golders Green to the south in 1907, the line being extended to Hendon Central, Colindale and Edgware in 1923/24.
Much of the area developed into a suburb of London and now the area is mostly built-up with some countryside in the Mill Hill area, such as the Copthall Playing fields.
Hendon's industry was mostly centred on manufacturing, and included motor and aviation works, and developed from the 1880s.
Hendon’s main claim to fame relates to the early days of flying and Hendon Aerodrome is now the world famous RAF Museum. Pioneer aviator Claude Grahame-White is closely associated with the area. On another part of the aerodrome site is the Hendon Police College, the training centre for the Metropolitan Police.
The River Brent runs through Hendon which also boast many parks and open spaces.
Today Hendon offers a wide range of housing from one bedroom apartments through to large family homes and offers an excellent choice of private and public schooling, shopping and recreational facilities.
